Octave band definition

Octave band means a spectrum of sound frequencies between band edge frequencies an octave apart. For purposes of this procedure, octave band frequencies are as specified in Table 1 of ANSI S1.11-1966 (R-1976) “specifications for octave, half-octave and third-octave band filter sets” (see N.J.A.C. 7:29-2.12(a)1).
